I agree that the plant on your web site is correctly identified as Huperzia phlegmaria. The one in the attached images you sent is H. nummulariifolia (Blume) Chambers, Jermy & Crabbe. Its wide elliptic leaves, appressed to the stem, are unique within the genus, as far as I know. Both are Old World species, and my expertise is primarily on New World tropical ferns, so I don?t have any interesting stories to tell you about them--sorry! I do, however, have two books that might help you in the future with information for your web site. One is about fern cultivation: Fern Grower?s Manual (with first author Barabara Joe Hoshizaki) and the other is A Natural History of Ferns (Timber Press, 2004). The latter is a popular (i.e., non-technical) book about ferns and lycophytes. It is not an identification guide, but tells about what ferns are doing in nature. Many of the things you mention on your web page for H. phlegmaria are also discussed in that book.
Good luck with your web site!
